🔧 Altima - Side View Mirror Replacement

Replacing a side view mirror on your Altima involves removing the interior front door trim panel, unplugging the mirror connector, unbolting the mirror, and installing the new mirror assembly. Your SL mirror may include power adjustment, heat, turn signal, and possibly memory functions, so the replacement mirror should match the original features.

Difficulty Level: Beginner to Intermediate | Estimated Time: 1-2 hours per side

⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before unplugging door electrical connectors to reduce the chance of short circuits.
• ⚠️ The front door trim has plastic clips that can break if pulled at the wrong angle. Use a trim removal tool, not a screwdriver, whenever possible.
• ⚠️ Support the mirror with one hand before removing the last nut so it does not fall and scratch the door paint.
• ⚠️ If your replacement mirror has a turn signal, puddle lamp, heat, or memory wiring, make sure the connector style matches before fully reassembling the door.

📋 Before You Begin

• Park your Altima on level ground and turn the ignition OFF.
• Lower the window on the door you are working on. This gives you more room to hold the door panel safely.
• Apply painter’s tape around the outside mirror base to protect the paint.
• Disconnect the negative battery cable using a 10mm socket. Wait at least 2 minutes before unplugging door connectors.
• A trim removal tool is a flat plastic pry tool used to pop panels loose without scratching them.
• A torque wrench is a tool that tightens fasteners to a measured tightness so small studs are not broken.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Protect the Door and Mirror Area

• Use painter’s tape around the painted edge where the mirror meets the door.
• Put on safety glasses and work gloves.
• Tape prevents accidental scratches.

Step 2: Disconnect the Battery

• Open the hood and use a 10mm socket with a 1/4-inch ratchet to loosen the negative battery terminal.
• Move the negative cable away from the battery post so it cannot spring back and touch.

Step 3: Remove the Inner Door Handle Trim

• Use a small flat-head screwdriver wrapped with tape to gently lift the small cover behind the inside door handle.
• Remove the exposed screw using a Phillips #2 screwdriver.
• Place the screw in a cup or magnetic tray so it does not get lost.

Step 4: Remove the Door Pull Trim and Screws

• Use a plastic trim removal tool to lift the trim cover in the door pull area.
• Remove the screw or screws underneath using a Phillips #2 screwdriver.
• Work slowly. The trim cover is plastic and can crack if twisted hard.

Step 5: Release the Door Panel Clips

• Slide a plastic trim removal tool between the lower edge of the door panel and the metal door shell.
• Gently pry outward to pop the retaining clips loose.
• Continue around the lower and side edges of the panel until the clips release.
• If a clip stays in the door, remove it with the plastic trim removal tool and reinstall it onto the panel before reassembly.

Step 6: Lift the Door Panel Off

• Use both hands and lift the door panel straight upward to unhook it from the top window ledge.
• Hold the panel close to the door because electrical connectors are still attached.
• Unplug the switch connectors by pressing their locking tabs with your fingers or a small flat-head screwdriver.
• Set the door panel on a clean towel to avoid scratches.

Step 7: Remove the Mirror Sail Panel

• The sail panel is the small triangular interior trim piece at the front upper corner of the door.
• Use a plastic trim removal tool to gently pry the sail panel away from the door.
• Pull it straight outward to release the clips.

Step 8: Unplug the Mirror Connector

• Find the mirror wiring connector inside the door near the mirror mounting area.
• Press the connector lock and unplug it by hand.
• If the lock is stiff, use a small flat-head screwdriver to gently press the tab while pulling the connector apart.

Step 9: Remove the Mirror Mounting Nuts

• Support the outside mirror with one hand.
• Use a 10mm socket, 6-inch socket extension, and 1/4-inch ratchet to remove the mirror mounting nuts.
• Keep the socket straight so the nuts do not fall inside the door.
• If a nut drops, use a magnetic pickup tool to retrieve it.

Step 10: Remove the Old Mirror

• From outside the door, gently pull the mirror away from the door.
• Feed the wiring connector through the opening in the door.
• Check that the old foam seal did not stick to the door. Remove it by hand if needed.

Step 11: Install the New Mirror

• Make sure the mirror foam seal or gasket is seated flat on the new mirror.
• Feed the mirror wiring through the door opening by hand.
• Place the mirror studs into the door holes while supporting the mirror from outside.
• Start all mounting nuts by hand first to prevent cross-threading.

Step 12: Tighten the Mirror Nuts

• Use a 10mm socket, 6-inch socket extension, and torque wrench inch-pound range to tighten the mirror nuts evenly.
• Torque to 8 Nm (71 in-lbs).
• Do not overtighten. The mirror studs can break.

Step 13: Reconnect and Test the Mirror

• Plug the mirror connector back in by hand until it clicks.
• Temporarily reconnect the negative battery cable using a 10mm socket.
• Turn the ignition ON and test mirror adjustment, heat, turn signal, and memory function if equipped.
• Turn the ignition OFF and disconnect the negative battery cable again using a 10mm socket before finishing reassembly.

Step 14: Reinstall the Sail Panel

• Align the sail panel clips with the holes in the door.
• Press the panel into place by hand until the clips snap in.

Step 15: Reinstall the Door Panel

• Reconnect the door switch connectors by hand until each connector clicks.
• Hang the top of the door panel over the window ledge.
• Align the door panel clips with the holes in the door.
• Press around the edges by hand to lock the clips into place.

Step 16: Reinstall Screws and Trim Covers

• Use a Phillips #2 screwdriver to reinstall the door pull screw or screws.
• Use a Phillips #2 screwdriver to reinstall the inner door handle screw.
• Snap the trim covers back into place by hand.

Step 17: Reconnect the Battery

• Reconnect the negative battery cable.
• Use a 10mm socket and 1/4-inch ratchet to snug the terminal clamp.
• Torque to 5 Nm (44 in-lbs) if using a torque wrench.
